Cloud sandboxes
for AI agents.

Firecracker microVM sandboxes with sub-200ms cold starts. Full Linux environments. Hardware-level isolation. Per-second billing. Simple REST API.

example.js
// Create a sandbox
const res = await fetch('https://sandbox.developersdigest.tech/api/v1/sandboxes', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json',
  },
});
const sandbox = await res.json();

// Execute a command
const exec = await fetch(
  `https://sandbox.developersdigest.tech/api/v1/sandboxes/${sandbox.id}/exec`,
  {
    method: 'POST',
    headers: {
      'Authorization': 'Bearer YOUR_API_KEY',
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ command: 'pip install pandas && python analysis.py' }),
  }
);
const result = await exec.json();
console.log(result.stdout);

// Kill the sandbox when done
await fetch(
  `https://sandbox.developersdigest.tech/api/v1/sandboxes/${sandbox.id}`,
  { method: 'DELETE', headers: { 'Authorization': 'Bearer YOUR_API_KEY' } }
);

Features

Built for speed.

Every sandbox is a Firecracker microVM with its own Linux kernel. No shared kernel. No container escapes.

Speed

Sub-200ms cold starts

Firecracker snapshot restore. Your sandbox is ready before your LLM finishes generating the next token.

Security

Hardware-level isolation

Each sandbox is a Firecracker microVM with its own Linux kernel. The same tech that powers AWS Lambda.

DX

Streaming output

Real-time stdout/stderr via SSE. Watch your agent's code execute live with streaming callbacks.

Flexibility

Full Linux environment

Run any language, install any package, start any process. Root access to your own Linux machine.

Cost

Pause & resume

Snapshot full VM state to disk. Resume later exactly where you left off. Pay nothing while paused.

Infra

File system & networking

Read, write, and watch files. Expose ports with public URLs. Full network access inside the sandbox.
